    If you need to provide multiple additional certificates, the 'extracerts' argument needs to be an array with one certificate per element:
    <?php
    $args     = array(
            'extracerts' => array(
                0 => '-----BEGIN CERTIFICATE----- cert1 ...',
                1 => '-----BEGIN CERTIFICATE----- cert2 ...',
                // ...
                )
        );
    ?>

    You can use this to prepare a PEM.

    <?php
    $pemChain     = '...';
    preg_match_all('/(-----BEGIN CERTIFICATE-----.*?-----END CERTIFICATE-----)/si', $pemChain, $matches);
    $args = array('extracerts' => $matches[0]);
    openssl_pkcs12_export($signed_csr, $cerificate_out, $private_key_resource, $passphrase, $args);
    ?>

    If your certificate is not password-protected, just use null or a blank string.  Otherwise, this function won't work.

    If you want to include CA-Certificates in the PKCS12 it can be accomplished by using the $args parameter.
    <?php
    $args     = array(
                       'extracerts' => $CAcert,
                       'friendly_name' => 'My signed cert by CA certificate'
                      );
    openssl_pkcs12_export($signed_csr, $cerificate_out, $private_key_resource, $passphrase, $args);
    ?>

    in order to export a private key to pkcs12 format, the input certificate must contain both private and associated public key in PEM format , 

    -----BEGIN RSA PRIVATE KEY-----
    -----END RSA PRIVATE KEY-----

    -----BEGIN CERTIFICATE-----
    -----END CERTIFICATE-----

    else this function might return the following error "openssl_pkcs12_export(): cannot get cert from parameter 1"

    Example:

    <?php
    $key     = openssl_pkey_get_private(Private_Key, Password);

    openssl_pkcs12_export(Certificate, $iis, $key, Password);
    ?>
